Sharp COCOROBO RX-V60 Compatible Battery 16V 3000mAh

Sharp COCOROBO RX-V60 / RX-V80 / RX-V90 / RX-V100 — 16V LiFePO4 Replacement Battery (UBATiA001VBKZ)

This is a 16V LiFePO4 replacement battery for the Sharp COCOROBO robotic vacuum cleaner range. It fits the RX-V60, RX-V80, RX-V90, RX-V100 and six additional COCOROBO variants. Capacity is 3000mAh (48Wh), matching the original specification.

• COCOROBO series compatibility: The RX-V60 through RX-V100 share the same 16V battery platform and connector format. All run the same BMS handshake, so the UBATiA001VBKZ and cross-referenced part numbers (UBATiA003VBKZ, F-4991-810-1, LIS5003SPP) all apply across this lineup without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the COCOROBO platform. The BMS responded correctly to the dock charger's handshake, accepted a full charge without fault codes, and held voltage under sustained drive-motor load on both hard floor and carpet-resistance profiles.
• Dock charging discipline: Do not leave the COCOROBO sitting on its dock permanently between cleaning sessions. Continuous trickle charge through the dock accelerates capacity fade in LiFePO4 cells at this form factor. Charge to full, then remove the unit from the dock until the next use.

Suction dropping before the battery indicator reaches low

This happens when the drive motor draws more current than rated — usually caused by a partially blocked filter or brush roll restriction. The BMS responds to the elevated draw by reducing cell output voltage before the indicator circuit registers a low-battery event. The vacuum loses suction, but the LED still shows charge remaining. Clear the filter and brush roll first. If suction recovers immediately, the battery is not the cause — the restriction was forcing the motor above its normal draw threshold.

Motor cuts out mid-cycle and then restarts on its own

This is a BMS overcurrent trip, not a dead battery. When the COCOROBO transitions from hard floor to carpet, motor load spikes sharply. If the filter is even partially blocked at that moment, current demand exceeds the BMS trip threshold and the cell disconnects to protect itself. The unit then restarts once the BMS resets — typically within a few seconds. Clean the filter until airflow is unrestricted, then confirm the resting pack voltage reads at or above 15.2V before the next run.
